I can't help but think that power losses in a good extension cord are probably negligible. Provided you get a nice super heavy duty extension cord with 12 AWG or higher wire, the resistance of a 20' cord would easily be less than .1 Ohm. If you were pulling 20 amps through the cord, that'd be 2 volts you'd lose to the cord. I have been informed by my father that the power company delivers us 120VAC +/- 10%. So you'd really have to worry more about the power company stiffing you on any particular day, I'd think.
